Unit membrane model was put forward in the year 1953 while studying cell under electron microscope. The basic unit membrane structure was considered to be general for a wide variety of plant and animal cells. All cell organelles such as Golgi body, mitochondria, endoplasmic reticulum, nuclear memb...
As the basic fabric of the plasma membrane, the phospholipid (a bilayer lipid) has a number of characteristics/features that contribute to its functions.Some of these characteristics include: AmphipathicAs an amphipathic structure, the phospholipid bilayer has regions that are hydrophilic and ...

plasma membrane n.a thin membrane (a double layer of lipids) enclosing the cytoplasm of a cell; proteins in the membrane control passage of ions (like sodium or potassium or calcium) in and out of the cell 同义词:cell membranecytomembrane ...
In plant cells, the plasma membrane is a highly elaborated structure that functions as the point of exchange with adjoining cells, cell walls and the external environment. Transactions at the plasma membrane include uptake of water and essential mineral nutrients, gas exchange, movement of metabolites...
Structure of the plasma membrane Phospholipid molecule A phospholipid molecule has: a polar head (includes a phosphate group) Nonpolar tails (fatty acids) The polar phosphate group A key component of living things is water Water is polar The polar phosphate group allows the cell membrane to intera...
Structure of the Membrane The plasma membrane is composed of TWO layers of phospholipids back to back The phospholipid bilayer is made up of: A Hydrophilic head that is attracted to water A Hydrophobic tail that is NOT attracted to water (scared of water). ...
is the essential structure. The components are inside and outside of the cell, according to the cell layer. Another basic element of the cell membrane is membrane proteins that are inserted within the lipid structure. One of the primary functions of membrane proteins is associated with transport...
The influence of the plasma treatment conditions on the basic properties of the membranes, namely pore size and pore shape, porosity and mechanical strength has been studied. It was arranged that the effect of air plasma on the PET TMs results in etching a membrane's surface layer. The ...
